Why doesn't Roo (1.2.2) use Hibernate 4 instead of 3.6.9.Final?

Hello,

I had a problem with a count query that I've solved by updating the maven dependency from 3.6.9.Final to 4.1.3.Final

So I wonder why doesn't Spring Roo use the last release instead of a previous version.

Well, I read some complaints about Hibernate 4, and I'm not sure of the version of JDK that H4 requires. Maybe those are some of the reasons.

Thank you very much.

I have used count query many times -without any problem- with non H4 releases...
I might be wrong but don't think that is the problem.

Anyway. What are the H4 complaints that you are referring to?

Thank you!

Thanks for the response.

The problem is a count for an entity with a composite key. Hibernate translates "select count(o) from Entidad o" as select(o.id1, o.id2) from t_Entidad o" (you imagine the JPA Entity )

It doesn't work in some databases (DB2 Z/OS, mysql in windows)

Regarding the Hibernate 4 complaints, I don't rember right now a concrete example, maybe it was the typical rants when a new big release appears.
